Section1, Section 2 and Overall score for each website are presented as mean of all questions (8 questions in Section 1, 7 questions in Section 2, 15 questions overall). Values are averages corrected to one decimal place. Websites are listed in rank order of overall score. Scores can range 0 to 5 where a score less than 5 suggests some ‘potentially important but not serious shortcomings’ and a score of less than 3 suggests some ‘potentially serious shortcomings’ in the information. BTA = British Tinnitus Association, CKS Clinical Knowledge Summaries. Inter-rater reliability is reported as Kendall’s Wt. ‘Used by% GPs’ refers to the proportional use of each website by GPs in our previous study [6].
